What is the function on a sperm cell and how is it adapted to complete this?
Fertilise an ovum (egg)
- tail to swim to the ovum
- lots of mitochondria to release energy from respierstion enabling the sperm to swim
What is the function of a red blood cell and what are it’s adaptations?
Transport oxygen around the body
-no nucleus so more room to carry oxygen
-contains haemoglobin that bines to the oxygen molecules
-flat bi-concave disc shape to in crease surface area to volume ratio
What is the function of muscle cell and how is it adapted to do this?
Contract and relax to allow movement
-contain protein fiebres that contract to make cells shorter
-contain lots of mitochondria to release energy from respiration allowing the muscles to contract
What is the function of a nerve cell and how is it adapted to do this?
Carry electrical impulses around the body
- branched endings called dendrites to make connections with other neurones
-myelin sheath insulates the axon to increase the transmission speed of electrical impulses
What is the function of a root hair cell and how is it adapted?
Absorb mineral ions and water from the soil
- long projection speeds up the absorption by increasing the cell surface area
- lots of mitochondria to release energy for the active transport
What is the function of a palisade cell and how is it adapted?
Enables photosynthesis in the leaf
- lots of chloroplasts containing chlorophyll to absorb light energy
- locales at the top surface of the lead where it can absorb the most light energy
